By placing a yellow arrow with a code on it in specific locations, visitors can text message a site which will provide videos, directions and information about the location. In this case, community members have produced a tour of Washington DC and 10 landmark areas in the early DC punk scene.
On the website, there are video podcasts/online mini-documentaries based on each landmark. Some of the features include stories told by Ian Mackaye, Alec Mackaye (Untouchables, the Faith), Dante Ferrando (Gray Matter), Brendan Canty and Joe Lally (Fugazi), Allison Wolfe (Bratmobile) and Ian Svenonius (Nation of Ulysses) and even an interview with ex-DC mayor Marion Barry (infamously caught doing crack on camera in a FBI sting back in the late 80s.
You can find more about the walking tour here.
